Everyone says to avoid big trucks when going out. Why are big trucks so dangerous?

Speaking of this topic, you can first understand the relevant content of large trucks:

Novices are always told to stay away from big trucks when driving on the road. On the way, besides being drunk, the most terrible thing was the big truck. What I want to say today is, how dangerous is the big truck? Why is it so dangerous?

Big guy? Trucks that are really dangerous are a general term for a class of vehicles. Specifically, there are many kinds of them, such as semi-trailer tractors, heavy engineering vehicles with four front wheels and eight rear wheels, and heavy engineering vehicles with eight rear wheels. Simply put, they are classified according to size. The weight of the first four wheels and the rear eight wheels is 16 tons, and the load of sand is about 60 tons, with a total weight of about 75 tons. The rear eight-wheeled vehicle weighs 13 tons, carries about 40 tons of cargo and has a total weight of about 53 tons.

The total weight of some large trucks pulling steel can even reach 120 tons. What is the concept of 120 ton? Ordinary cars generally weigh only about 1.5 tons, while tanks weigh only 60 tons.

Are big trucks really prone to accidents, or do you speak with numbers?

In 20 12, the accident rate of 10,000 vehicles in national road traffic accidents was about 15, while the accident rate of 10,000 vehicles for trucks was 30% higher, which was 19.58. What does this number mean? In other words, an average of 10,000 trucks will cause 19.58 accidents a year.

Does it look okay? Statistics will scare you. According to statistics, from 2008 to 20 12, operating trucks accounted for 7.8% of the total number of motor vehicles in China, causing 27.7% of fatal traffic accidents, accounting for 15.8% of the total number of major road traffic accidents with more than one person killed 10. The lethality of big trucks has caught up with that of big killers.

Look at the danger of truck accidents. According to the above statistics, the fatality rate of truck accidents is 0.32, which means that an average of three accidents will lead to one death. This figure is 52% higher than the death rate of road traffic accidents in China.

Among the trucks that cause accidents, heavy trucks are the most deadly. They caused 57.4% of the total number of truck accidents, while light trucks only accounted for 65,438+03.7%.

Let's take a look at the accident investigation of the highway in a mountainous area in northern China by the key experiment of Tongji University Road and Traffic Engineering, Ministry of Education. Among the vehicles passing through here, the proportion of heavy trucks is less than 365,438+0%, resulting in 53.6% accidents and nearly 60% casualties.

From all aspects, the big truck is indeed a well-deserved maruta killer.

Why do big trucks become deadly killers? According to the first volume of junior high school physics textbook, the greater the mass of the object, the greater the inertia.

When the speed of an ordinary car is 100 km/h, the braking distance is 40 ~ 45 m, while the braking distance of a large truck is more than 50 m when it is empty. If the truck is fully loaded, the braking distance can be from 100 m to 1000 m. ..

When a large truck is driving under heavy load, if it brakes fully, the loaded goods will rush forward due to inertia, even flatten the front of the car, or flatten the cockpit and the driver with iron sheets. Semi-trailer tractor is more dangerous. If its front wheel braking ability is better, it is sometimes worse than the rear wheel braking, the front of the car slows down, and the car is still moving forward. What will happen to the front and the front? Fold? Together, it is easy to roll over. For safety reasons, many drivers canceled the front wheel brake. This has become a hidden rule in the industry.

Another hidden rule is overload. More than 80% of truck road traffic accidents are caused by overloading. This question has been said a lot, so I won't go into details here. In short, the tragic braking ability of large trucks is even more tragic because of overload.

?

Then, the danger of trucks is self-evident. As an ordinary driver, we often try to avoid big trucks, because there are many car accidents caused by big trucks every year, which is also a very serious accident. Once it happens, it is difficult to guarantee the driver's life safety. After all, the size and weight of the truck are there. Don't risk your life at any time, let alone increase the size of the truck at will. This is also very dangerous.

Generally speaking, large trucks are very dangerous. When you go out, you must pay attention to avoid them, otherwise an accident will have serious consequences.
